Application filed. Tanuary 17,1914. Serial No. 812,657.

Be it known that 1, NM J. KEMZPF, a

citizen of the United States of erica, re-

siding at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Wrapping-Machine s, of which the following is a specification. I

This invention relates to wrapping ma chines. It is a very common practlcein wrapping many articles, such for instance as bars of chocolate, to inserta card mthe package formed by the wrapping operatlon.

Sometimes this card serves merely for ad-- vertising purposes, but more frequently it is used for the purpose of stifiening the package and protecting the wrapped article from breakage. The handling' f a plurality of pieces of wrapping materlal in this manner requires .a relatively complicated mechanism; and this is particularly true in machines designed to wrap food stufis, or confections, which require more than one wrapper. For instance, cakes of chocolate are usually wrapped in a tin fo1l or other moisture-proof wrapper, and also m an outer wrapper or band, the .card being 1nserted between the inner wrapper and the band. v

The present invention aims to simplify the mechanisms designed to handle wrapping materials of this character; and 1t 1s d1 .rected specifically to the solution of the problems presented in introducing'a card into a package. The manner 1n whlch 1t 1s proposed to solve these problems Wlll be readily understood from the following description of a machine similar to that shown in {Patent No. 895,945, granted August 11, 1908, the machine of this patent, however, being modified in accordance with the present invention. A r

In the specific machine hereinafter described it is proposed to make use of some suitable adhesive material to efiect the transfer of a card with a wrapper or band with which it is to be associated, and thus to avoid the necessity of a separate card transferring mechanism.

In the drawings: Figure 1 1s a top plan view of a part of my machine; Fig. 2 is a.

sectional view taken on the lines of Fig. 1 of the mechanism for handlmgthe paper wrapper and the band; Fig. 3 1s a sectional view of the machine taken on the lines 3-3 of Fig.1; Fig. A is a side eleva- In its general arrangement, my machine is broadly similar to that disclosed in the patent to Berger above referred to and the wrapping mechanisms, shears, etc., are operated in the same fashion. For that'reason,

they have not been shown in the drawings, -which rather are concerned with the real subject-matter of the invention which is the manipulation and insertion of a card between the paper wrapper and the band prior to the actual wrapping-operation.

In the drawings, the supporting framework of the machine is represented by A. The main-shaft 1, supported in the'framework A, carries a large driven-gear 2 and drives by bevel-gears the counter-shaft 3 supported in brackets 4' upon the framework A. The paper feed is not shown in detail, it being understood that this mechanism is substantially like that shown in the Berger patent above referred to. It will be suflicient here to say that the paper ;0 is fed through a depression 5 in the top-plate 6 of the machine and cut off at the appropriate moment by shears 7. Located at the rear of the depression 5 in the plate 6 in my machine are a pair of brackets 8 upstanding from the frame-work A which carry a small shaft 9 upon which is a daub wheel 10 having a projecting lug 11 thereupon.

Associated with one of the brackets 8 is a bracket 12 which carries the short shaft 13 driven by the sprocket 14 and carrying at its opposite end the lugs 15. A glue-box 16 is seated in a recess in a plate 16' secured to the frame-Work A above the path of the paper, this glue-box carrying bearings for the shaft 17 which carries the wheel 18; and the box is removably secured inplace by the hand-screw 19, the arrangement beings'uch that the entire glue-box may be removed for cleaning merely by the loosening of the hand-screw 19. The shaft 17 carries upon its ends a pair of lugs 20 for cooperation with the lugs 15 whereby, when inserted in place, the shaft of the glue-box is positively rotated from the shaft 13. Upon the shaft 6 adhesive devices 10'-11 have placed a small positively rotated to apply a small patch of adhesive to the paper passing thereunder each time lugll on wheel 10 comes in contact'with the paper, the lug 11 in turn taking (up adhesive from the wheel 18. This adhesive mechanism is driven by the chain 25 from a sprocket upon the counter-shaft 3 as clearly shown in Fig. 2.

a The forward end or as shown in Figs. 1 and 3 and comprises a ing a shoulder to carry forward the bottom Located above the depression 5 in the topplate 6 of the machine is the band-magazine having at one side thereof the suction withdrawing device 31, substantially like that disclosed in the Berger patent above referred-to, and. operable from the side of the band-magazine toward the shears 7 is a nipper 32, as suggested in Fig. 1, adapted to seize the leading end of leading end of the wrapping. paper together and to draw these two wrappers to the wrapping elements of the machine, all in the fashion shown in Berger, save that I here ems ploy and find it necessary to use only one nipper where Berger uses an independent nipper for the band and for the wrapping paper, respectively. A path-cam 40 u on the main-shaft 1 drives the reciprocating slide 41 in a manner clearly shown in Fig. this slide is forked pair of prongs 42. (only one of which is shown in Fig. 3) and a small plate 44 formcard of a pile of cards 45 carried in a suitably arranged l receptacle 46 and pressed downwardly by the Weight 47 all as shown m Fig. 3. Upon each reciprocation of the slide 41, a card is introduced thereby above the .wrappin paper p and beneath the bot tom plate '0 the band-magazine 30 and located substantially centrally ofthe wrapping paper in the recess 5 of the top-plate 6. Upon the counter shaft 3 is a cam 50 cooperating with a roller 51 upon a reciprocable shaft-52 sliding inbearings 53 upon' the frame-work A and carrying at its upper .endthe block 54 which reciprocates in the recess 55 in the top-plate 6 substantially midway thereof. This mechanism serves to force the card and the paper together at the point where adhesive is supplied between the two .whereby the card and paper will thereafter adhere to each other as the paper is drawn through the machine, and the forks 42 on slide 41 may be withdrawn without disturbing the card.

The operation of my machine is briefly as follows: The wrapping paper is fed through the recess 5 from an indefinite supply. The

display or covering bands are supplied to t e1r magazine 30. With the parts in the position illustrated in Fig. 1, the slide 41 introduces a card above the wrapping paper 7) and below the bottom-plate of the bandmagazine. Previous to this operation, the

the band and thefications,

paper and the card together against the bottom-plate of the band-box, and the fork withdraws to the position shown in Fig. 3 whereit is ready to introduce the next card. After this operation, it'will be obvious that thecard and the paper are stuck together by a very small patch of adhesive not large enough to mar the appearance of the card but still large enough to hold the two together. After this operation, the suctionbox 31 is operated to present the leading end of a band, as shown in Fig. 2, and the m per 32 advances andin one grab grips the cading end of band and the leadmg end of the wrapping paper and then moves off to the wrapping elements of the machines, the shears 7 operating at the proper time to sever the proper length of wrapper. It will readily be understood that the result of these operations is\to present for wrapping upon the article a band and a piece of wrapping paper with a card sandwiched therebetween.

In Fig. 5, I have shown a modificationof my device which concerns the application of adhesive to the card, either in addition. to

the application of adhesive to the wrapping paper or as a substitute therefor. In this modification, I have provided a path-cam upon the transverse-shaft 3 of the machine which operates the plunger 61 located in a glue-box 62 immediately under the ile of cards 45. In this construction, the pl linger 61 moves up to apply aidab of adhesive to the underside of the post card just before the forked slide 41 removes this card from the pile.

It is to be'understood that in both modithe forked structure of the slide 41 is such as to hold the card so that the adhesive either upon the card or upon the wrapping paper, as the case may be, will not be touched by the other as the card is introduced, until the contact-block 54 makes a connection between the two.

Having now particularly pointed out and described my invention, but well knowing that many changes and modifications may be made from the specific forms in which I have chosen here to illustrate it without departing from the broad scope of the invention, which is more truly bounded and defilned by the claims hereto appended, I c a1m:--

g. 3. In introduc a device operative thereafter to transfer said card and wrapper simultaneously to the wrapping elements of the machine.

2. In a wrapping machine, the combination with a band positioning mechanism, a

10. In a wrapping machine, means for feeding a wrapper, means for feeding a card, means for applying adhesive to one of the parts so fed, means to locate the card in proximity to the wrapper without disturbing the adhesive, and means to thereafter press said card and said wrapper together upon the adhesive.
